PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 414,679, dated November12, 1889.

Application filed June 26, 1889. Serial 110315553. (Model) T (LIZ whom,it 71mg concern.- Be it known that I. EDWARD E. CLAUSSEN, of Hartford,Connecticut, have invented a new and useful Paper Bag, of which thefollowing description and claim constitute the specification, and whichis illustrated by the accompanying three sheets of drawings.

This invention is a novel paper bag which has a flat rectangular bottomin combination with two flat sides, and it is made from a plain flatpaper tube instead of being made from a tucked paper tube, such as haveheretofore been generally used for making paper bags with fiatrectangular bottoms.

Figures 1 and 2 of the drawings are aside view and an end view of a flatpaper tube. Fig. 3 is a view of the blank of Figs. 1 and 2, with one endopened out and folded down into a diamond form. Figs. Aland 5 are a planand an edge view respectively of the blank of Fig. 3, with the left-handhalf of the diamond form of that blank folded forward toward theright-hand half thereof, so as to be directly over it. Figs. 6 and 7, 8and 9, 10 25 and 11, 12 and 13, and ll and 15 are five pairs of views ofthe blank of Figs. 4 and 5 at five successive stages of its subsequentmanipulation in the process of folding. Fig. 16 is a view of thecompleted bag which results from the next and last step of the pro cessof folding. Fig. 17 is an isometric perspective view of the bag of Fig.16 opened out with its bottom upward. Fig. 18 is a view of the exteriorof the bottom of the bag of Fig. 17, and Fig. 19 is a view of theinterior of that bottom. Figs. 20 and 21 are a plan and an edge viewrespectively of the bag of Fig. 16 with the left-hand half of the bottomthereof folded forward over the right-hand half of that bottom, with aview to being packed with othersuch bags in a bundle. Figs. 22 and 23,2a and 25, and 26 and 27 are three pairs of views of the blank of Figs.at and 5 at three successive stages of its subsequent manipulationtoward producing the modified form ofmy new bag which is shown in Figs.28 and 29, Figs. 22 and 23 being identical with Figs. 6 and 7,respectively. Fig. 30 is an isometric perspective View of the completedbag of Figs. 28 and 29 opened out and bottom upward.

The process of making the bag of-Fig. 16 is as follows: The flat papertube 1 of Fig. 1 is opened out. at one end into the diamond form shownin Fig. 3 by folding the upper ply thereof backward on the line 2 3, soas to produce the diamond form 4. Paste is then applied to that diamondform at the locations indicated by the stippled surface. The lefthandhalf of the diamond form is then folded forward above the right-handhalf thereof. The forward or lower half thereof is then held down uponany suitable fiat surface at the places 5 and 6, and the upper halfthereof is gripped at the places 7 and 8, and the blank at those placesis raised upward and backward through an arc of a circle, of which theline 11 12 is the axis, as far as to the position shown in Figs. 6and'7, thus producing the truncated triangular flaps 9 and 10, and the flattriangular diagonal sides 13 and 11, and the flat rectangular endsurfaces 13 and 1%, which latter extend from base to base of thetruncated triangular flaps 9 and 10. The diagonal side 13 and therectangular end surface 13, and also the corresponding side and surface14 and 1e, are then bent inward along their mutual longitudinal centersrespectively, while the upper flap 10 is lowered somewhat to permit thatinward bending, and the blank is thus folded into the form shown inFigs. 8 and 9. Thereupon the blank is pressed and held down upon thefiat surface beneath it by any straight-edged implement placed thereonimmediately to the left of the line 16 17. Then the upper flap 10 iscarried upward and backward through an arc of a circle, of which theline 16 17 is the axis, to the position shown in Figs. 12 and 13, andthence still farther to the position shown in Figs. let and 15. Theeffect of this operation is to produce the pockets 20 and 21,which arebounded on one side by the bends 22 and 23, respectively, and thosebends constitute the defining-lines of the ends of the rectangularbottom of the bag when the bag is completed. That completion consists infolding the end of the flap 9, as it appears in Figs. 14 and 15, overupon the end of the flap 10, as shown in Fig. 16. The completed bag maythen be packed in a bundle with others; or, if desired, the left-handhalf of its rectangular bottom may first be turned over upon theright-hand half thereof into the position shown in Figs. 20 and 21.

The process of making the bag of Figs. 28 and 29 is identical with thatof making the bag of Fig. 16 as far as the stage shown in Figs. 6 and 7,and also shown in Figs. 22 and 23 but in this case, after that stage isreached, the blank, at the places 7 and S, is carried backward anddownward in an arc of a circle, the axis of which is coincidentwith theline uniting the places 5 and-6. This latter transaction maintains theflatness of the rectangular end surfaces 13' and 14, and it folds thepaper at the outer boundaries of those surfaces and between them and thetriangular diagonal sides 13 and 14, respectively, and thus produces thedefining-lines 22 and 23 at the ends of the rectangular bottom of thebag, and it also folds each of those triangular diagonal sides in-wardin two unequal triangular parts, so that the smaller of those parts anda portion of the larger of those parts lie under the adjacentrectangular-end surface, and so that those triangular diagonal sides aremade to constitute the folds 26 and 27, respectively, of the completedbag.

larger printing-s11 rface than that of the Honiss bag, and in the otherconsequent result of having only two weakening longitudinal creases,instead of six, in the main part of the body of the bag.

I claim as my invention A paper bag having a flat body, a flatrectangular bottom, and folded triangular folds extending from the endsof the bottom toward the center of the bottom and then reversed andextending to the two edges of the flat body, respectively, allsubstantially as described.
